Fuel Pump Relay

Where is the Fuel Pump Relay Can anyone tell me where the fuel pump relay is on a 1993 S-10 pickup with the 2.8L V-6 motor? I am having a fuel cell installed in the bed and the pump is located in the frame rails, and the shop doesn't know where the fuel pump is to wire into for power. I want the pump to turn on with the ignition (not with a switch), so I need to know where it is located. Thanks for any help.

Underhood at firewall.
#6 and #7
the number on the relay should be 10034222

there is also a tan or white wire on the firewall that you can run 12 volts to that will kick your fuelpump over for testing...
